For much of the past decade, the Tennessee Titans have attempted to build their roster around a strong, physical defense that had the ability to set the tone early.
While those attempts have often come up short, none have failed quite as spectacularly as the 2012 defensive unit.
The Titans surrendered 29.4 points per game last season, the most in the NFL, and also finished near the bottom of the league in yards allowed, takeaways and overall time of possession.
Following the disastrous year, the Titans entered an offseason in which significant change was desperately needed.
Over the course of the last few months, the Titans have taken steps to rebuild the unit. The Titans added Gregg Williams as a senior assistant and signed a number of free agents that are in line for significant reps once the season rolls around.
However, for the unit to work its way into the top half of the league, the Titans must see improvements from some of the young players they hope to build their defense around.
